1.1 Introduction

The LPC11Exx are an ARM Cortex-M0 based, low-cost 32-bit MCU family, designed for

8/16-bit microcontroller applications, offering performance, low power, simple instruction

set and memory addressing together with reduced code size compared to existing 8/16-bit

architectures.

The LPC11Exx operate at CPU frequencies of up to 50 MHz. The peripheral complement

of the LPC11Exx includes up to 32 kB of flash memory, up to 8 kB of SRAM data memory,

one Fast-mode Plus I2C-bus interface, one RS-485/EIA-485 USART with support for

synchronous mode and smart card interface, two SSP interfaces, four general purpose

counter/timers, a 10-bit ADC, and up to 54 general purpose I/O pins.

The I/O Handler is a software library-supported hardware engine that can be used to add

performance, connectivity and flexibility to system designs. It is available on the

LPC11E37HFBD64/401. The I/O Handler can emulate serial interfaces such as UART,

I2C, and I2S with no or very low additional CPU load and can off-load the CPU by

performing processing-intensive functions like DMA transfers in hardware. Software

libraries for multiple I/O Handler applications are available on http://www.LPCware.com.

For additional documentation, see Section 24.2 “References”.
